A shortened term for anabolic steroids, a hormone group injected into the bloodstream that rapidly increases the rate of tissue growth, particularly muscle. Roid usage is most common amongst younger athletes and wannabe bodybuilders with no brains, no patience, no dedication, and no actual strength. Those who use roids literally trade their balls for fast muscle growth, as if taking years off their lives was not enough.

Instead of being a real man by working hard, eating right, and being dedicated, Roger decided to cheat and use roids. He was diesel in a few weeks, but couldn't take off his shirt because of his horrible bacne problem, and couldn't bang any of the chicks he met because he can't get it up anymore. Now he's pretty much back where he started. Way to go, Roger.
